<span>Roan is a combination of white hairs with red hairs. When we see cattle like this, they look pink because it resulted from a mix of white and red.
Red allele: A
White allele: a
</span>
<span>A heterozygotic animal has this genotype: Aa
Like i said previously this is the mixture of colors so the animal would be pink.
A red coat color has this genotype: AA
A white coat color has this genotype: aa
To get all the herd to be</span><span> roan-colored cattle the combination of parents should be: AA x aa. -> 100% roan
Another possible way to obtain would be</span><span>roan-colored cattle: Aa x Aa or aa x Aa (in this case there would be less probabable to obtain road).</span>
Breathing into and out of a paper bag for a long period of time will lead to respiratory acidosis.
<h3>
What is respiratory acidosis?</h3>
- When the lungs are unable to expel all of the carbon dioxide the body produces, a condition known as respiratory acidosis develops.
- Body fluids, particularly the blood, become too acidic as a result.
- The main causes of respiratory acidosis are inadequate ventilation and carbon dioxide buildup.
- The main issue is an increase in arterial carbon dioxide partial pressure (pCO2) and a decline in the arterial bicarbonate to arterial pCO2 ratio, which causes a drop in blood pH.
- When there is acute respiratory acidosis, the body initially tries to make up for it.
- If the acidosis lasts more than 12 hours, a reaction known as metabolic compensation2 takes place.
- By increasing the release of hydrogen ions through ammonium, the kidneys will lower the blood's acidity.
- Too much carbon dioxide in the body can result in general symptoms including headache, exhaustion, and twitching muscles.
- Frequently, it goes away fast on its own.
- But in cases of severe hypercapnia, the body is unable to return to a stable CO2 level, and the symptoms are more severe.

<span>DNA stands for deoxyribonucleic
acid. The deoxy- in the DNA is a short term for deoxyribose. The nucleic acid
molecule has three parts; sugar, phosphate and a base. The phosphate in the DNA
acts as a backbone of the molecule. It is also responsible for the DNA’s
‘double-helix’ structure. The base has four codes namely adenine, thymine,
cytosine and guanine. Adenine and thymine are bse pairs whereas cytosine and
guanine are base pairs. They are not to be interchanged. Resulting in one cause
mutation in the gene. </span>
